A youngster was airlifted to hospital after being hit in the face with fireworks in Tūrangi on Saturday night.
Tūrangi Police are disappointed that a group around Te Kapua Park, who then went into the centre of town, got out of control with children setting off fireworks dangerously, firing at each other, at gardens and buildings.
Sergeant Te Reipa Morunga of Tūrangi Police says a tree in the car park was also set alight, requiring a call out by the fire brigade.
"I know they are also disgusted in the behaviour with the risk of more fires in town that night.
"Guy Fawkes was a bit of an issue for us in the way that people were using fireworks. One of [the] kids got injured, hit in the face. It's all fun and games until someone has to go to hospital.
